Description

Permanent magnetism magnetic floats linkage

Affiliated technical field

The utility model relates to the linkage of machinery, and particularly a kind of permanent magnetism magnetic float linkage, is fit to the be used as power equipment use of rotating torque greatly of needs of motor.

Background technology

In prior art, a lot of plant equipment all are used as power with motor, between motor and equipment, often only adopt union joint to make linkage, but there is the assembly precision height in union joint always, installation is complicated and the operation noise is big, weak points such as mechanical friction loss of energy.In addition, present linkage also is not provided with the device that increases rotating torque, therefore, is difficult to satisfy the requirement of some equipment, and this is the weak point of prior art just.

Summary of the invention

The purpose of this utility model is to provide a kind of operate steadily reliable, transmission noise and mechanical wear all smaller and can increase the floating linkage of permanent magnetism magnetic of rotating torque.

Above-mentioned task realizes by this way: a kind of permanent magnetism magnetic floats linkage, it is characterized in that by main motor, driving wheel, driven pulley, power output shaft, flywheel and auxiliary wheel are formed, driving wheel is placed on the main machine shaft, power output shaft is placed in rotating shaft the place ahead by the bearing supporting with main machine shaft coaxial line, driven pulley is socketed on the driving wheel and with power output shaft and is connected, flywheel is arranged on two power output shafts between the bearing, below flywheel, be provided with and be no less than two auxiliary wheels at least, on the excircle of driving wheel, some vertical permanent magnet blocks evenly are set on the inner periphery of driven pulley and on the excircle of flywheel and auxiliary wheel, the polarity of the permanent magnet block between driving wheel and driven pulley and the opposite face of the permanent magnet block between flywheel and the auxiliary wheel is identical, and the running clearance between running clearance between driving wheel and the driven pulley and flywheel and the auxiliary wheel is 0.5～1.5 millimeter.

The purpose of this utility model can also realize by the measure of giving:

The cross section of described permanent magnet block is suitable with 10 * 10 millimeters～15 * 15 millimeters, and the distance of adjacent two permanent magnet blocks is to be not more than its width for well.

On auxiliary wheel, also be provided with a stand-by motor, be convenient to the flywheel rotation and rotate more steadily.

Operation principle of the present utility model is such: during use, the defeated axle of equipment and power is connected just can.After starting main motor, driving wheel just rotates by the magnetic drive driven pulley,, meanwhile, also orders about flywheel and rotate under the rotation of power output shaft to the equipment power output that connects by power output shaft, increases the rotating torque of output shaft.Because driving wheel is to be in the floating state work of magnetic under the magneticaction of the relative magnetic patch of same polarity with driven pulley, do not contact mutually, and also under the floating state of magnetic, rotate between flywheel and the auxiliary wheel, make the rotation of flywheel can not produce too much rotation pressure, significantly reduced the wearing and tearing between power output shaft and the bearing bearing.Therefore, the running noise of whole linkage is seldom, and flywheel rotates also very steady, thereby can produce bigger rotating torque, make the equipment that connects with it can obtain enough power, in addition, motor is set on auxiliary wheel, more helps flywheel starting and stability of rotation.Therefore, the utlity model has reliable, the advantage such as noise is little and rotating torque is bigger that operates steadily, effectively overcome the deficiency of prior art.The utility model is particularly suitable for requiring the equipment that noise is little, output torque is bigger to adopt.
